Answer:

Stephanie sprinted 550 yards.

Step-by-step explanation:

Given that,

Stephanie ran three sprints during practice.

Her first sprint was 175 yards, her second sprint was 150 yards, and her third sprint was 225 yards.

We need to find the total distance that Stephanie sprinted. It is simply equal to the sum of all above sprints.

Distance = 175 yards + 150 yards + 225 yards

= 550 yards

Hence, Stephanie sprinted 550 yards.

Answer:

Step-by-step explanation:

we have a rectangle that measure 21 inches by 16 inches

to find the rectangle(which is the hypotenuse)  we will use Pythagorean theorem

c^=a^2+b^2

c^=21^2+16^2=697

c=[tex]\sqrt697}[/tex] =26.40 which rounded to the nearest tenth =26

Answer: the first graph

Step-by-step explanation:

The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The correct option is A.

The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At the y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

Given f(x)=2, therefore, the graph will have a y-intercept as 0.

But when the value of f(x) = 2(x) + 2, then the graph of the function will have the y-intercept at 2.

Hence, the correct option is A.

Answer:

x = 3 or x = 7

Step-by-step explanation:

X² - 8x + 14 = 2x - 7

x² - 8x + 14 - 2x + 7 = 0

Now we have a quadratic equation ;

x² - 10x + 21 = 0

-3 and - 7 gives a sum of - 10 and a product of 21

x² - 3x - 7x + 21 = 0

x(x - 3) - 7(x - 3) = 0

(x - 3) = 0 or (x - 7) = 0

x = 3 or x = 7

Answer:

Step-by-step explanation:

The question has missing details, as the diagram of the prism is not shown.

However, I'll solve using a general rule.

The volume of a triangular prism is:

[tex]Volume = \frac{1}{2}* b * h * l[/tex]

Where

[tex]b = base[/tex]

[tex]h = height[/tex]

[tex]l = length[/tex]

Take for instance:

[tex]b = 20cm[/tex]

[tex]h = 10cm[/tex]

[tex]l = 5cm[/tex]

The volume is:

[tex]Volume = \frac{1}{2} * 20cm * 10cm * 5cm[/tex]

[tex]Volume = 10cm * 10cm * 5cm[/tex]

[tex]Volume = 500cm^3[/tex]

Another instance (see attachment).

From the attachment:

[tex]b = 4.5cm[/tex]

[tex]h = 5cm[/tex]

[tex]l = 8cm[/tex]

The volume is:

[tex]Volume = \frac{1}{2} * 4.5cm * 5cm * 8cm[/tex]

[tex]Volume = 2.25cm * 5cm * 8cm[/tex]

[tex]Volume = 90cm^3[/tex]

Answer:

m = 1/4 or 0.25

Step-by-step explanation:

1/2 = 2m

[Symmetric property of equality]

2m = 1/2

÷2. ÷2

[Division property of equality]

m = 1/2 ÷ 2

m = 1/4

________

1/2 = 2m → 1/2 = 2(1/4) → 1/2 = 2/4 →

1/2 = 2÷2/4÷2 → 1/2 = 1/2

Answer:

n = 0.75

1 : 0.75

Step-by-step explanation:

To get from 8 to 1, you have to divide by 8. You do that to the number 6.

6/8 = 3/4 = 75/100.

Therefore, n = 0.75.

Answer:

9 pieces of candy.

Step-by-step explanation:

The information about how many boys there are is irrelevant, so we can just ignore that.

The important information is that the teacher has 396 pieces of candy and that it is split between 44 students equally.

So, to solve, we just do 396 / 44 = 9.

Therefore, each student will get 9 pieces of candy.

Answer:

[tex]\huge\boxed{\angle\text{CUE}}[/tex]

Step-by-step explanation:

We can model what both readings of this angle would be. Angle names are usually formed by taking the two lines that form to intersect this angle at a vertice, and these 3 make up the name.

Angle ∠CUT would be formed by the lines CU and UT. We can see that this is not the case, as the angle is formed by lines CU and CE.

Since they intersect at point U, that means the angle name would be CUE.

Hope this helped!

Step-by-step explanation:

Perimeter = 2 * (Side A + Side B)

= 2 * (3x + 2 + x - 5)

= 2 * (4x - 3)

= 8x - 6.

We have 8x - 6 = 50, so 8x = 56 and x = 7.

Answer:

YES. (2, 7) is a solution of the system.

Step-by-step explanation:

System of linear inequalities has been given as,

y ≥ -x + 1 --------(1)

y < 4x + 2 ------(2)

If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.

By substituting the coordinates of point (2, 7) in inequality (1),

7 ≥ -2 + 1

7 ≥ -1

True.

By substituting the coordinates of point (2, 7) in inequality (2),

7 < 4(2) + 1

7 < 9

True.

Therefore, point (2, 7) lie in the solution area of system of inequalities.

YES. (2, 7) is a solution of the system.
